“…It is also possible that after the grafts have been reduced by resorption to a certain size, the preservation method no longer influences the process. Apart from these considerations , graft resorption occurred in a manner similar to that described in the literature [6,17,[22][23][24][25] Thus, the present study showed no advantages of one method over the other, since the grafts were well tolerated in both cases and the resorption rates were the same after 60 days. However, larger grafts or other tissue grafts may behave differently.…”

“…Allogeneic transplants preserved in glycerol undergo faster substitution by bone than preserved autogenous material [16] . Removal of the perichondrium enhances substitution of the preserved material [17]. Transplantation of auricular cartilage preserved in 70% alcohol into surgically created periodontal defects in monkeys showed similar results to fresh autogenous and allogeneic grafts, the osteogenesis being proportional to the period of preservation [18] .…”

A comparative study was made of two methods of cartilage preservation, 98% glycerol and 70% alcohol. Rib cartilage was treated by either of these methods and transplanted into the malar proccess of rats. Cartilage grafts preserved by both methods were equally well tolerated. Resorption and bone substitution were similar in both groups after 120 days, although resorption was greater for the alcohol-preserved cartilage up until day 30. The possible reduction in antigenicity by the 98% glycerol did not produce any difference of behavior from the cartilage preserved in 70% alcohol.

O presente estudo avaliou, histologicamente, a utilização de implantes homógenos de matriz óssea na reconstrução do assoalho orbitário. Foram utilizados 22 ratos (Rattus, norvegicus, albinus, Wistar), sendo que quatro (4) constituíram o grupo de animais doadores da matriz óssea e o restante (18), formaram um único grupo. O lado direito (lado tratado) de cada animal recebeu implante ósseo e o lado esquerdo (lado controle) não recebeu qualquer tipo material, apenas o preparo do leito receptor simulando clinicamente, a perda de substância óssea após fratura cominutiva do assoalho e rebordo infra-orbitário. Foram sacrificados seis (6) animais, nos tempos pós-operatórios de 10, 25 e 45 dias. Após observação e discussão dos resultados, pôdese concluir que o processo de reparo no lado controle finalizou com neoformação óssea aos 45 dias; não houve processo intenso de reabsorção dos implantes de matriz óssea desmineralizada nos períodos estudados; ocorreu precoce proliferação conjuntiva e ossificação junto às matrizes implantadas.

The gold standard material for bone regeneration is still autologous bone, a mesenchymal tissue that consists mainly of extracellular matrix (ECM) (90% v/v) and little cellular content (10% v/v). However, the fact that decellularized allogenic bone grafts often present a clinical performance comparable to autologous bone grafts demonstrates the crucial role of ECM in bone regeneration. For long, the mechanism by which bone allografts function was not clear, but recent research has unveiled many unique characteristics of ECM that seem to play a key role in tissue regeneration. This is further confirmed by the fact that synthetic biomaterials with composition and properties resembling bone ECM present excellent bone regeneration properties. In this context, ECM molecules such as glycosaminoglycans (GAGs) and self-assembly peptides (SAPs) can improve the performance of bone regeneration biomaterials. Moreover, decellularized ECM derived either from native tissues such as bone, cartilage, skin, and tooth germs or from cells such as osteoblasts, chondrocytes, and stem cells has shown promising results in bone regeneration applications. Understanding the role of ECM in bone regeneration is crucial for the development of the next generation of biomaterials for bone tissue engineering. In this sense, this review addresses the state-of-the-art on this subject matter.
